Five investors normally sit on the main UK Dragons' Den panel.
The standard British format presents entrepreneurs to a group of five “dragons.” Each investor has a separate background, investment style and area of business experience, giving the pitch a broader test than a presentation to one backer. Entrepreneurs must respond to questions from the panel and may receive offers from one or several investors.
The number is sometimes confused with the number of dragons appearing in a particular episode. Scheduling, availability and special episodes can affect who is visible on screen, while the regular panel structure is built around five positions. Historical line-ups have also changed as investors joined or left the series.
The five-person arrangement is part of the format's dramatic design. It creates competition among investors and gives entrepreneurs the possibility of comparing different offers, valuations and conditions rather than receiving a single verdict.
